How do nutrients influence the bioavailability and distribution of drugs? Illustrate with suitable examples.

Leave a Comment / Nutritional Biochemistry /

Introduction The interaction between nutrients and drugs is a significant topic in nutritional biochemistry and pharmacology. Nutrients can affect how drugs are absorbed, distributed, metabolized, and eliminated from the body. This is known as a nutrient-drug interaction. Such interactions can influence the bioavailability (the amount of drug that reaches the bloodstream) and the distribution (how

Give two examples each of NAD and FAD dependent enzymes. Also name the vitamins from which these cofactors are derived.

Leave a Comment / Nutritional Biochemistry /

Introduction Enzymes are biological catalysts that speed up chemical reactions in the body. Many enzymes require additional molecules known as cofactors to function properly. Two of the most important cofactors are NAD (Nicotinamide Adenine Dinucleotide) and FAD (Flavin Adenine Dinucleotide). These are involved in oxidation-reduction (redox) reactions and are derived from vitamins. In this answer,
